Margaret Frances "Peggy" McCauley was born on April 22, 1929 in Norwood, Ohio to William Albert and Leona Mae (Bach) McCauley. Her parents divorced in 1931, and she moved to Manchester, Indiana to live with her aunt and uncle (F. M. and Margaret Hutchison) in 1932. She attended Manchester Elementary School for eight years and graduated from Aurora High School in Aurora, Indiana, in 1946. McCauley married Russell G. Fogle, an Army private stationed on Governor's Island (New Jersey), on June 30, 1950. The couple had three children: Jonathan Gayle, Rebecca Bach, and James Stephen. Russell and Peggy Fogle divorced in 1970, and Peggy moved to Baton Rouge, Louisiana, in 1971. She began working for the Taylor Building Company, where she remained until taking a job at Louisiana State University as a secretary in the Department of Philosophy in 1976. In 1978, LSU professor David Madden convinced Fogle to read Evelyn Scott's Escapade. The work left a deep impression on Fogle, who, despite the fact that she had only a high school education, dedicated the rest of her life to studying and bringing recognition to Evelyn Scott's work. Using the pseudonym Peggy Bach, she published the first Scott bibliography, wrote twelve essays about the author, and began work on Scott's authorized biography. Unfortunately, she had not yet finished her work at the time of her death from cancer on June 5, 1996.

Evelyn Scott (1893-1963) was born Elsie Dunn in Clarksville, Tennessee. In 1913, Elsie married Frederick Creighton Wellman, and they changed their names to Evelyn Scott and Cyril Kay-Scott. The couple moved to Brazil, where they had one son in 1914, Creighton Jigg Scott. After her divorce from Cyril in 1928, Evelyn married novelist John Metcalfe in 1930. Between 1921 and 1941, she wrote several books, including critically acclaimed The Wave and Eva Gay. After her final book The Shadow of the Hawk failed in 1941, she wrote two more unpublished novels.
